Increasing the volume of air that reaches the alveoli and takes part in gas exchange will cause blood pH to:
Karolina [17]

Answer:

B. increase, because the partial pressure of CO2 in the blood will decrease.

Explanation:

The presence of carbon dioxide gas in blood imparts H+ ions due to its reaction with H2O and thereby, lowers down the blood pH.

When more air reaches alveoli, the rate of gaseous exchange is increased. More of the carbon dioxide is removed from the blood and is released out of the body via exhalation.

Removal of carbon dioxide from blood would increase the pH of the blood since the partial pressure of CO2 in the blood would decrease.

True [87]

Answer:

Gene: The hereditary material made up of alleles.

Alleles: The alternative forms of a gene.

Dominant: An allele or trait that masks the effect of recessive allele or trait.

Recessive: An allele or trait that gets suppressed by the dominant allele or trait.

genotype: The genome of a particular organism of the genes which make up an organism.

phenotype: The physical traits or characteristics of an organism.

test- cross: A cross in which the dominant and the recessive trait offsprings are crossed to depict whether the dominant organism is homozygous or heterozygous.

law of independent assortment: Alleles of different genes get assorted independently into gametes.

law of segregation: allele pairs segregate during gamete formation and unite at the time of fertilization.

product rule: Independent evens can be calculated by multiplying the independent probabilities.

Addition rule: The probability which shows that one event would occur in a mutually exclusive event.

co-dominant: When the dominant and the recessive trait occur and the organism shows both the characteristics of the dominant and the recessive trait.

incomplete dominance: when the dominant trait is not fully dominant over the recessive trait. As a result, individuals are produced which show neither the dominant or the recessive trait. A new trait is developed in them.
